This is interesting. I have been having a terrible time with hacked sites and need some help

My site(s) were hacked at GoDaddy and I changed the NS to Bluehost and gave them fresh installs there and rebuilt one of them and bought and installed a brand new copy of Enfold. Yesterday, that template wasn’t working and I had a white screen. Bluehost says it’s the template…why would it have been working all week? They won’t help. They say it might be WordPress (don’t think so) and I can’t get it fixed. I also have 4 other sites that are also acting strangely, (older templates, not Enfold) not displaying any slideshows from plugins. This sounds systematic to me. Do I need to move my sites? Have you encountered this? Is it a matter of finding and deleting a file? bluehost isn’t helpful in identifying this for me and I am not sure what to do. The site has the latest version of WordPress. Could this be something in the hosting environment? Help!
Thanks,
Jay
